The Ls electric FSC series is a line of output Du/Dt filters built specifically for frequency inverters. These filters are designed to work smoothly with VFD systems, giving installers a reliable way to protect motors and control cables. Whether you are wiring a small 7.5kW drive or a larger 55kW unit, the FSC series covers the most common power ranges. Each model is tested to meet strict industrial standards, so you can trust it to perform day after day without unexpected failures.

Protect Your Motor and Cables

Voltage spikes and fast switching waves from inverters can damage motor windings and shorten cable life. The FSC output Du/Dt filter smooths out these sharp voltage changes before they reach the motor. This means less stress on insulation, fewer bearing currents, and a much longer service life for your equipment. For installers, this translates to fewer callbacks, lower maintenance costs, and happier end users who rely on steady machine operation.

Easy Installation and Compact Design

Time is money on every job site, and the FSC series is built to save both. The filters come in a compact housing that fits neatly into standard control cabinets without taking up extra space. Wiring is straightforward, with clearly marked terminals and simple connection steps that match common VFD output setups. You can mount them quickly, secure them with standard hardware, and get the system running faster. No special tools or complex tuning are required.

Reliable Performance in Tough Conditions

Industrial environments can be harsh, with heat, dust, and constant vibration. The FSC filters are built to handle these challenges without losing performance. They use high-quality components and effective heat dissipation to stay cool even during long runs. The sturdy casing resists moisture and mechanical stress, making them a solid choice for factories, water plants, and HVAC systems. You get consistent protection that does not drop off when conditions get tough.

Pick the Right Model for Your Drive

Matching the filter to your inverter power rating is simple with the FSC lineup. Use the FSC 3025 for 7.5kW drives, the FSC 3036 for 11 to 15kW units, and the FSC 3130 for 55kW systems. Each model is engineered to handle the exact current and voltage levels of its target drive, ensuring optimal filtering and full warranty coverage. Check your inverter specs, pick the matching FSC filter, and install with confidence knowing your system is fully protected.
